1. An optical fiber cable, comprising:
a central tube having a first inner surface and a first outer surface, wherein the first inner surface defines a bore along a longitudinal axis of the optical fiber cable;
at least one optical fiber disposed within the bore of the central tube;
a cable jacket disposed around the central tube, the cable jacket comprising a first material and having a second inner surface and a second outer surface defining a first thickness therebetween;
a skin layer disposed around the cable jacket, the skin layer comprising a second material and having a third inner surface and a third outer surface defining a second thickness therebetween, the second thickness being 100 μm or less; and
a pair of diametrically opposed strands disposed in the cable jacket, each strand of the pair of diametrically opposed strands comprising a plurality of strengthening yarns, each strengthening yarn having a linear density of 1000 denier to 2000 denier;
wherein the first material has a first coefficient of friction and a first coefficient of thermal expansion (CTE);
wherein the second material has a second coefficient of friction and a second CTE;
wherein the second coefficient of friction is less than the first coefficient of friction and the first CTE is less than the second CTE.
